The BQ29401PW from Texas Instruments is a BiCMOS secondary protection IC for 2-, 3-, or 4-cell Lithium-Ion battery packs. It incorporates a high-accuracy precision overvoltage detection circuit with a typical operating current of less than 2 µA when cell voltages are below the protection threshold.
This IC provides overvoltage protection at 4.45V with a typical tolerance of ±25 mV. It features a programmable delay circuit for overvoltage detection time, enhancing protection stability during pulse charge operations. The device is suitable for applications requiring second-level protection in Li-Ion battery packs.
The BQ29401PW is available in an 8-TSSOP package, designed for surface mount applications. Its operating temperature range is -20°C to 85°C. Key features include high accuracy over-sense voltage, programmable delay time, and high power supply ripple rejection.
Applications for the BQ29401PW include battery packs in notebook PCs, portable instrumentation, and medical and test equipment, where reliable battery protection is critical.
